I've coached out at ECR as well and here are some quick/easy points:
-Braking for T1 is downhill...I've seen several near misses and also some impacts here
-Try and make T3 one continuous arc
-T5 braking is downhill like T1 and can be a bit bumpy so give yourself a few extra feet
-T6 is not a full 180, so drive it like the increasing radius it is and tell yourself 'exit speed is life'.
-The last part of T9 the car is loading up pretty good and you can frequently go a good bit faster then you initially feel. However, find this speed in small bites.
-T10 is blind uphill and takes a bit to get right. Don't get frustrated if this corner takes a while
-T11 is like 3, but try and drive it so it is a increasing radius turn. That is, get a lot of the turn done early so you can accelerate out to the front straight carrying more speed than if you drove it like a constant radius corner.
